Hey! I have an STL I downloaded, and there’s a flat surface, aligned with the ground that I’d like to make some holes in. I can draw the shapes, but because the object is floating above/below the surface, any extrusion just adds material rather than subtracting it.
I suppose my question could be, how do I force an extrusion to be negative space rather than positive? I hope I’m describing this correctly.
STL’s can be tricky to work with. Here, the orange body is an STL object. I extrude a cylinder thru the STL and then subtract it.
Thanks TigerMike! I played around some more yesterday after posting, and that’s the same solution I came up with. It got me where I wanted to go.
Here’s another tidbit. Sometimes I make the STL semi-transparent (temporarily) so I can see how much I want to create a recess when I don’t want it all the way thru the part.
How did you make the box transparent?
You have to select and go through Visualization. Not sure if it is available in the free version of Shapr3D.
